BUILDING-BLOCK DIE.

SPECIFICATION forming part of Letters Patent No. 708,725, dated September 9, 1902.

Application filed April 17, 1902.

To all whom it may concern:

Be it known that I, NICHOLAS MERLEY, a citizen of the United States, residing at Canton, in the county of Stark and State ofOhio, have invented certain new and useful Improvements in Building-Block Dies; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the figures of reference marked thereon, in

\ which Figure 1 is a perspective view showing the outlet end of the die. Fig. 2 is a perspective view showing the inlet end of the die and its difierent parts. Fig. 3 is a longitudinal section. Fig. 4 is a view showing a finished building-block.

The present invention has relation to dies calculated and designed to produce hollow building-blocks from plastic clay; and it consists in the novel construction hereinafter de-.

In the accompanying drawings, 1 repre-' sents the outershell of the die,"which is formed of a size to correspond substantiallywith the size of the block, it being understood that the inner dimensions of the shell are to correspond with the outer dimensions of the block to be produced. WVithin the shell 1 is located the core 2, which is formed of a size to give the desired thickness to the shell of the building-block, and of course the distance between the inner surfaces of the shell 1 and the outer faces of the core 2 will be the thickness of the shell of the block.

The shell 1 is provided with a flange 3, which flange is for the purpose of providing a means for connecting the herein-described die to the end of the machine used to force the plastic clay through the die. The ma chine proper forms no particular part of the present invention, and hence it is not illustrated, as it will be understood that various kinds and styles of machines can be used without any reference to my improved die.

To the flange 3 or its equivalent are connected or formed integral therewith posts or Serial No. 103,306. (No model.)

arms 4, to which posts or arms are securely attached the cross-bars 5, which cross-bars are for the purpose of attaching and holding in proper position the core 2. For the purpose of causing the plastic clay to move past the end of the core said core is beveled substantially as illustrated in the drawings, it being understood that any angularity of the bevel may be provided, as thisis a matter of judgment only.

In the construction of building-blocks it is important that the shell thereof be provided with openings for the reception of mortar or cement, so as to properly bind the adjacent ends of the building-blocks together when placed in a Wall. To accomplish this object and purpose, I provide anydesired number of bars or cores 6, which bars or cores may be located and arranged as shown in the drawings, or they may be diiferently arranged, reference being had to the number of apertures ,designed'to be formed in the finished block and their location. Should it be desired to press upon one face of the building-block any desired configuration by any of the well-known means, the bar or core 6 may be dispensed with upon that particular side, this, however, beinga matter of judgment in the manufacture of the blocks.

The bars or cores 6 are attached to the crossbars 5 by means of suitable angle-bars 7 or their equivalents, as it will be understood that it is immaterial as to the exact manner of connecting the bars or cores, except that they must be so connected that they will extend parallel through the space between the inner surface of the shell 1 and the outer surface of the core 2.

die angled extensions 8, which angled extensions are flush at their inner ends with the inner face of the shell, but are ,beveledas they extend away from the shell, the angled extensions 8 being beveled in each direction,

so as to free the plastic clay in a gradual this difficulty I connectto'the corners of the ing clean and smooth-cornered building blocks.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of an outer shell or die provided with a flange, a core located within the shell and spaced from the inner sides thereof, posts or arms connected to the flange of the shell, cross-bars secured to the posts, bars or cores located in the space between the outer shell and the inner core and extended parallel with the inner and outer faces of said parts, and the cross-bars and the inner core beveled upon their rear edges or ends, substantially as and for the purpose specified.

2. A die of the class described, an outer shell, a core located therein, and angled extensions secured to the shell of the die and provided with inner beveled faces, substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two Witnesses.

NICHOLAS MERLEY.
